50 Years of Americans in Orbit

Fifty years ago today, John Glenn was the first American to orbit the Earth. For some reason, Alan Shepard, Jr. being the first American in space did not impress me as a kid. Going up and coming back down did not count. Achieving orbit was realer space. Glenn was the American response to Yuri Gagarin being the first human to orbit the Earth on 12 April 1961.
